ATTACHMENT FOR BURNERS.

SPECIFICATION forming part of Letters Patent No. 568,703, datedSeptember 29, 1896. Application filed December 12,1895. Serial No.571,942. (No model.)

To all whmn it may concern:

Be it known that I, WALTER TYLEE Ross, of the city of Montreal, in thedistrict of Montreal and Province of Quebec, Canada, have inventedcertain new and useful Improvements in Attachments for Burners; and I dohereby declare that the following is a full, clear, and exactdescription of the same.

My invention has for its object to provide a simple and effectivearticle adapted to be cheaply manufactured and sold to householdersusing lamps of any of the well-known description having removable glasschimneys or globes, such article intended to be set in place beneath thelamp-chimney to furnish to the flame inclosed therebyanevenly-distributed supply of pure air in addition to and at a pointabove the usual supply of air through the burner proper. The article isin the form of a ring provided with ventilatingopenings therethrough,and this ring is, as before mentioned, adapted to be set in placebeneath the chimney, and with the latter, of course, removably restingupon same. For full comprehension, however, of my invention referencemust be had to the accompanying drawings, forming a part of thisspecification, in which Figure 1 is a side elevation of a portion of aburner of an ordinary coal-oil lamp with my improved detachableair-supplying ring and the lower portion of an ordinary chimney restingthereon, but not in any way attached thereto; Fig. 2, an enlargedtransverse vertical section thereof. Fig. 3 is a detail perspective viewof the outer ring, and Fig. 4 is a detail perspective view of the ringproper removed from the lamp.

The detachable air-supplying ring, constructed in the cheap and simplefashion hereinafter described, is capable of ready application to any'of the usual lamps in use, since all that is necessary in using same isto remove the chimney, place the ring in position so as to rest looselyupon ordinary chimneygallery of the burner, and replace the chimney,which will, of course, now be loosely supported on the ring instead ofon the burner, as formerly.

The ring 5 is preferably formed with inwardly-projecting flanges 6 7 atits top and bottom edges, respectively, the upper one, 6, being widerthan the lower one in order to provide a surface upon which the chimney8 may be supported, and between such edges the openings 9, preferably ofoval outline, are formed in the body of the ring.

If desired, an outer ring 10,having openings 11 correspondingto theopening in ring 5, may be used, as shown in Fig. 2, and is preferablyslightly larger than such ring 5 in order that it may be set around sameand held thereon by friction only.

My detachable air-supplying ring is first set in place upon the burner12, when the wick can be ignited, the chimney set in place upon thering, and the lamp be ready for use.

The device constitutes a cheap and simple article, which can be soldseparately by lampdealers for detachable application to almost everyexisting form of lamp without in any way altering their construction,and the result of its use is noticeable in a striking increase in theilluminating power of the lamp.

What I claim is as follows:

1. As a new article of manufacture, alampventilator consisting of a ringcut away in part to provide air-inlets,adapted to be detachablyinterposed between the burner proper of a lamp and the chimney thereofand to rest loosely on the ordinary chimney-gallery of the burner, andupon the upper edge of which ring the chimney can rest loosely, for thepurpose set forth.

2. As a new article of manufacture, a portable lamp-ventilatorconsisting of a perforated ring having a flange on its upper edge,adapted tobe detachably interposed between the burner proper of a lampand the chimney thereof and rest loosely on the ordinary chimney-galleryof the burner and to extend above the usual ventilated surface thereofand loosely support the chimney, for the purpose set forth.

3. In a lamp, the combination with the burner and the chimney or thelike thereof, of a portable air-supplying device consisting of a ringprovided with inwardly-projecting flanges at its upper and lower edgesand such ring having openings therethrough between such flanges, and thewhole removably located intermediate of such burner and chimney, for thepurpose set forth.

Montreal, December 9, 1895.
